A little while back I tried to make a dual boot with ubuntu mint to see how that operating system is, I was a bit disappointed tho because of some issues I had, so decided to remove the partitions for ubuntu mint from my C drive.

Now, a game that took my 3 seconds to load, now shows the same loading screen for about 30 seconds. From having a fluid gameplay, I suddenly get a lot of short freezes.

I removed all software related to my GPU and then re-installed the - still the same issue.
It seems like something has made my GPU run on just 10% of its normal power. Yesterday I also messed around a bit and it went up to about 50% of its normal power, it went back to being super slow after the night however for some reason.

The issue is not the heat either. The card is new and my chassis peaks around 50c when being used for gaming.

I don't think it is the CPU either as GPU friendly tasks seem to be handled very well. Even switching between programs while waiting on the slow load time of the game goes really fast.

if so you can try restoring your system to date before last week.If that not helps try running crystal disk info(checking your disk) and crystal disk mark(hdd speed test,select largest size in test), run stress test for cpu and gpu.Meybe you can try to do clean install of OS. What game is it?

I don't think the problem is your GPU, because of all the driver re installs that you did.

You said putting the GPU back to 50% power made it run fast, and then slow again the next day? How old is your PSU? Old PSU's can cause a lot of problems.

My PSU isn't that old either, around a year old and it is an 800 watts PSU on a build recommending 500 watts.

Tho it worked earlier when I still had 800 watts and from what I know then it only gives what is asked for, so if the computer needs 536 watts, it gives 536 watts. Merely that it has to capacity to reach up to 800 watts.

Correct. Do you happen to have a spare graphics card around? Or better yet, another PC you can put your 770 in? You could test it in another PC to see if the problems persist.

Sadly, I have no computer that is close to mine, so changing the GPU wouldn't really help as I got a lot faster RAM memory than them and a lot faster CPU etc.
My fastest other card is the HD 7770 from radeon, but it is a lot slower than the one I have now, so it would again not really help. Sadly.

I am trying to update to the latest beta driver available atm from nvidia and we'll see what happens.
Otherwise I may try tomorrow to change cards back to the HD 7770 to see if it is faster than the GTX 770.

Would a benchmark test be able to test this theory that it's the GPU?

The wattage ratings on power supplies are capacity ratings. An 800W PSU can handle up to or close to 800W under specific conditions. Having more than enough power than needed is never a bad thing.

Obviously, having a 300W PSU when you're pulling 500W, for instance, will cause several issues including, but not limited to, not allowing all components to power up completely.

The CPU is hanging a bit after, but the average is still in-between gaming laptop and high-end gaming computer (closer to the latter).

I'll remove the game and install it again and we'll see what happens.

I put up a lot of hardware monitors while starting that game.
Nothing got capped except my HDD that randomly decided to be capped.
The GPU was around 80% on memory and core clock, the CPU was around 12% and the RAM took around 6 out of 32 GB.
This is really frustrating.

It didn't use to, but now it can randomly freeze. Especially when there's a lot of special effects at the same time.

Motherboard: ASUS SABERTOOTH 990FX
PSU: Corsair PowerSupply (PSU) GS 800W Gaming Series 80 Plus
GPU: Gigabyte GeForce GTX 770 4GB
CPU: AMD FX-8150 3.6GHz 8-Core
RAM: Corsair Classic XMS 32GB DDR3 PC-10666 1333MHz CL9
HDD: Hitachi HDT725025VLA380 SCSI

EDIT: By "it didn't use to", I mean before last weekend.

I tried to restore the system to an earlier date, but it failed so I made a clean install now of the OS.

The game is Warframe.
